UITableView Edit mode

提问by user739509

I have UITableViewand I am trying to load it by default in edit mode. The problem is when I this line table.editing=TRUE;my rows disappear, I implemented this methods:

我有UITableView并且我正在尝试在编辑模式下默认加载它。问题是当我这一行table.editing=TRUE;我的行消失时，我实现了这个方法：

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath 
{
// Return NO if you do not want the specified item to be editable.
return YES;
}

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath 
{
return UITableViewCellEditingStyleDelete;
}


 - (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath 
 {
 return NO;
 }

but with no luck. What should I do?

但没有运气。我该怎么办？

as Anishpointed to using

正如安尼什指出的那样使用

[tableView setEditing: YES animated: YES]; 

But you need to have it in viewWillAppearview event to make it work.

但是您需要在viewWillAppear视图事件中使用它才能使其工作。

In ViewDidLoad write

在 ViewDidLoad 中写入

UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style: UIBarButtonItemStyleBordered target:self action:@selector(addORDoneRows)];
[self.navigationItem setLeftBarButtonItem:addButton];

addORDoneRow

添加ORDoneRow

- (void)addORDoneRows
{
    if(self.editing)
    {
        [super setEditing:NO animated:NO];
        [_dbSongsTblView setEditing:NO animated:NO];
        [_dbSongsTblView reloadData];
        [self.navigationItem.leftBarButtonItem setTitle:@"Edit"];
        [self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStylePlain];
    }
    else
    {
        [super setEditing:YES animated:YES];
        [_dbSongsTblView setEditing:YES animated:YES];
        [_dbSongsTblView reloadData];
        [self.navigationItem.leftBarButtonItem setTitle:@"Done"];
        [self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStyleDone];
    }
}

For MultipleSelection of Row

对于多选行

 - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
    return YES;
}

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
    return UITableViewCellEditingStyleNone;
}

Note: There are Three Editiing Style as below

注意：有以下三种编辑风格

UITableViewCellEditingStyleNone,
UITableViewCellEditingStyleDelete,
UITableViewCellEditingStyleInsert

Note: And for multiple Selection set Selection and Editing Style to Multiple from Attribute inspector

注意：对于多个选择集，从属性检查器将选择和编辑样式设置为多个

To load a tableView in edit mode you should call setEditing(true, animated: false)in viewDidLoad().

要加载在编辑模式下的tableView你应该调用setEditing(true, animated: false)的viewDidLoad()。

If your view controller is a subclass of UITableViewControllerthere's no need to change, just make the above call. Otherwise if your view controller is a subclass of UIViewController, then you should make a call in this way: tableView.setEditing(true, animated: true).

如果您的视图控制器是UITableViewController不需要更改的子类，只需进行上述调用。否则，如果您的视图控制器的UIViewController的子类，那么你应该在这样一个电话：tableView.setEditing(true, animated: true)。

Tested with Swift 2.2.

使用 Swift 2.2 测试。

[self.tableView setEditing:!self.tableView.isEditing animated:YES];

[self.tableView setEditing:!self.tableView.isEditing 动画:YES];
